MH370 Mystery: Use Tow Sonar System.

The disappearance of MH370 six months ago was thought to occur after the jetliner deliberately diverted. All concerned have mapped an undersea area in the southern Indian Ocean,1800 km from Perth. They have discovered two vocanoes and very complicated sea floor.
    Malaysia, China, Australia and others have planned to spend months on the designated area to search for the wreckage. They use tow sonar system such as deep towed side scan sonar bought by Petronas. Boustead is said to contribute.
     In such a complex ocean floor, will the aircraft be found?  The search continues.
